Background

About Joydeep Das

I’m Joydeep Das - a scientific computing professional with hands-on experience at the Indian Institute of Science (IISc), where I’ve spent over 4.5 years building, optimizing, and deploying large-scale simulations across CPU and GPU environments: • 3× Simulation Speedup - Optimized plasma physics workloads using CUDA and OpenACC, running at scale on Perlmutter (NERSC, USA) and PARAM PRAVEGA (India) • Code-Level Expertise - Developed and improved research codes like GTC, G2C3, VMEC, and BEAMS3D for kinetic modeling and fast-ion dynamics • HPC Operations - Managed a 24-node, 1500-core HPC cluster (job scheduling, environment setup, user support) • Scientific Research - Worked on peer-reviewed work and mentored junior researchers in high-performance modeling • Early Foundation - Built custom Fortran-based polymer simulations at Amity University using MATLAB + GNUPLOT : Deep expertise in numerical simulations, code performance, and scientific software Strong background in Python, C++, Fortran, Linux environments, MPI, SLURM, and scripting Ability to design, scale, and automate simulation workflows from scratch Industry-ready experience in technical R&D, GPU acceleration, cluster optimization, and compute-driven problem-solving A practical mindset focused on real results, faster runtimes, and reproducibility I bring simulation insight, engineering depth, and code-level optimization - ready to support teams working at the intersection of science, engineering, and computation.
